As someone else pointed out, not all the world is Linux. So your version of Linux (I'm not sure whether it is true for all versions or not) delivers Python as part of the OS. That is simply not true of the whole world. Some OS distributions have an adjunct facility for installing packages but they are not part of the OS. Some systems don't even have that and people must download packages such as Python and install them manually. Even on Linux there are people who won't install binaries and use NetBSD's pkgsrc instead. Clearly that cannot install into /usr/bin since it is not part of the OS. Certainly #! /usr/bin/python is fine if you never expect your software to run outside of your own little corner of the world but you asked why people prefer the env version and the answer is that we want to write software that runs everywhere that Python runs. -- D'Arcy J.M.
